stack blendlevel with opaque controls?

I have this working on Windows, but to get it working on the Mac Rev  
will need to make a change to the way the windows are created  
(composite windows turned on).. That particular feature can only be  
turned on when the window is created, so either Rev has to do it or  
someone needs to find a way to intercept the window creation and add  
it.. Good luck with either of those..
